Definitions

  • the three-phase/biaxial coordinate converter 35 outputs the d-axis electric-motor current value id to the adder 75, and outputs the q-axis electric-motor current value iq to the adder 70.
  • the biaxial/three-phase coordinate converter 30 outputs the three-phase sine-wave command voltages Vu*, Vv*, and Vw* to the three-phase adder 32.
  • the three-phase sine-wave command voltages Vu*, Vv*, and Vw* are three sine-wave signal voltages each having a phase difference of 120 degree one another, and having the same frequency and amplitude.
  • FIG. 5(c) is a diagram showing a line voltage of the PWM drive voltage applied to the electric motor 7 in FIG. 2 .
  • Line voltages Vuv, Vvw, and Vwu each has an amplitude twice as much as the DC voltage E2, and are respectively applied between the U-phase terminal of the main body 22 of the electric motor 7 and the V-phase terminal thereof, between the V-phase terminal of the main body 22 and the W-phase terminal thereof, and between the W-phase terminal of the main body 22 and the U-phase terminal thereof.
  • FIG. 6 is a diagram showing a relationship between a phase voltage of the PWM drive voltage and a line voltage thereof.
  • the electric motor 7 generates auxiliary torque in accordance with steering wheel torque as the three-phase currents Iu, Iv, and Iw in accordance with the line voltages Vuv, Vvw, and Vwu flow through the electric motor 7.
